MAX5651

The MAX5650/MAX5651/MAX5652 parallel-input, voltage-output, 16-bit, digital-to-analog converters (DACs) provide monotonic 16-bit output voltage over the full extended operating temperature range. The MAX5650/MAX5651 include an internal precision low drift (10ppm/°C) bandgap voltage reference, while the MAX5652 requires an external reference. The MAX5650 operates from a +5V single supply and has a +4.096V internal reference. The MAX5651 operates from either a +3V or +5V single supply and has a +2.048V internal reference. The MAX5652 operates from either a +3V or +5V single supply and accepts an input reference voltage between +2V and AV_DD. The MAX5650/MAX5651/MAX5652 parallel inputs are double buffered and configurable as a single 16-bit wide input or a 2-byte input. The MAX5650/MAX5651/MAX5652 unbuffered DAC voltage output ranges from 0 to V_REF.

The MAX5650/MAX5651/MAX5652 feature an active-low hardware clear input (CLR) that clears the registers and the output to zero-scale (0000 hex) or midscale (8000 hex), depending on the state of the MID/ZERO input. These devices include matched scaling resistors for use with a precision external op amp (such as the MAX400) to generate a bipolar output-voltage swing.

The MAX5650/MAX5651/MAX5652 are available in a 32-pin, 5mm x 5mm TQFN package and are guaranteed over the extended temperature range (-40°C to +85°C).

For 14-bit, pin-compatible versions of the MAX5650/MAX5651/MAX5652, refer to the MAX5653/MAX5654/MAX5655 datasheet.

For 12-bit, pin-compatible versions of the MAX5650/MAX5651/MAX5652, refer to the MAX5656/MAX5657/MAX5658 datasheet.
